First, let me say congratulations and I wish you well!

It seems to me that no one is really trying to tell the OP what he can or can't do, rather they are offering their advice based on their individual experiences. (I see now that godwine beat me to this point, but I'll post it anyway.)

Because it just seems kind of morbid to quote divorce rates to a starry-eyed young man planning for his marriage, I will take a different approach to the same basic end. Love isn't something that needs to be rushed; if it's there, it will still be there a couple years down the line.

I'm sure that moving to a foreign country must be a huge stressor (even just moving to a new city is), and I know that marriage is. So are: pursuing an education, starting a career path, and supporting yourself in the world for the first time.

What I'm saying is that there is no reason to put your relationship through all of those stressors, all at once. Move to Japan, go to school, start a career, put down some roots -- all the while your relationship can develop into something even deeper than it is now, as you look forward to your future together. When you've got more stability, marry her.

More time never hurts.

(I will add that one of my best friends got married right out of high school and is still married, and happy, 22 years later.)
